that Ubayy bin Ka'b narrated that the Prophet ﷺ said: "The boy that Al-Khidr killed was destined to be a disbeliever the day he was created.'"
عَنِ النَّبِيِّ ﷺ قَالَ الْغُلاَمُ الَّذِي قَتَلَهُ الْخَضِرُ طُبِعَ يَوْمَ طُبِعَ كَافِرًا

عَنِ النَّبِيِّ ﷺ قَالَ الْغُلاَمُ الَّذِي قَتَلَهُ الْخَضِرُ طُبِعَ يَوْمَ طُبِعَ كَافِرًا
The boy whom al-Khidr had killed was created an infidel. Had he lived, he would have moved his parents to rebellion and unbelief.
قَالَ رَسُولُ اللَّهِ ﷺ الْغُلاَمُ الَّذِي قَتَلَهُ الْخَضِرُ طُبِعَ كَافِرًا وَلَوْ عَاشَ لأَرْهَقَ أَبَوَيْهِ طُغْيَانًا وَكُفْرًا

عَنِ النَّبِيِّ ﷺ الْغُلَامُ الَّذِي قَتَلَهُ صَاحِبُ مُوسَى طُبِعَ يَوْمَ طُبِعَ كَافِرًا

نَبِيُّ اللَّهِ ﷺ «إِنَّ الْغُلَامَ الَّذِي قَتَلَهُ الْخَضِرُ طُبِعَ يَوْمَ طُبِعَ كَافِرًا»
"الْغُلام الَّذِي قَتَلَهُ الخَضِرُ طُبْعَ يَوْمَ طُبعَ كَافِرًا وَلَوْ عَاشَ لأَرْهَق أَبَوَيهِ طُغْيَانًا وكُفْرًا" .
